Program flow control monitoring routine can be designed as module execution working time monitoring routine, and it has the module error-detecting of the free stamp of band. When it is write with C++, program flow control monitoring routine can be used in any module, and especially useful for the module write with C++. Action when it is write with C++, when C encapsulation (C-wrapper) can be used for fault. Consequently, it is desirable to less memory spending, each monitors module 32 byte. Corresponding program flow control monitoring routine does not need to use outside storer (namely using storage inside device) to provide the time to stab.
The program flow control monitoring routine write with C++ can realize at module therein. Given module can be designed to detection module mistake and take action, and need not depend on peripheral equipment/interface. Corresponding program flow control monitoring routine can to design towards object programming (ObjectOrientedProgramming:OOP) concept. Therefore, the amendment of monitoring mechanism is completed by adding/remove the attribute of monitoring (Monitor) class. In at least one embodiment, program flow control monitoring routine is towards object programming design, can reuse N time so that it performs monitoring for different modules. For providing for performing making an immediate response of fault with the interface routine of other application communications.
Reference Fig. 6, program flow control monitoring routine 600 comprises module monitors management routine 605 and the module list 610 treating to monitor by module monitors management routine 605. As shown in Figure 6, routine CMonitorMgr uses routine CCirDLinkList class to create module list to be monitored. Routine CMonitorMgr is independent of real time operating system (RTOS) (RTOS) function. Routine CMonitorMgr does not use the application programming interfaces of any real time operating system (RTOS) to obtain the information of the thread about monitoring. Routine CMonitorMgr605 and routine CMonitor_TimeMinMax615 all uses routine CSisTime class 620 renewal time stamp in each execution of program flow control monitoring routine. The time stamp upgraded is relevant with any module mistake detected.
With further reference to Fig. 6 and additionally with reference in the figure 7 as the table 1 shown in element 700, it provides the explanation 710 of function 705, function 705 by routine CMonitorMgr605,720 and routine CMonitor_TimeMinMax class 615,715 provide. Variable m_bEnabledMonitoring625 remains vacation, until routine CMonitor_TimeMinMax receives first time renewal by routine TriggerTime () 719. After receiving first time renewal, variable m_ulLastTriggerTime will be updated and variable m_bEnabledMonitoring will be written as very, and routine CMonitorMgr will check threshold time limit. Also not activating if monitored when routine CMonitorMgr calls inspection, so will not implement threshold time inspection. Routine CMonitorMgr can be configured in interrupt level or thread-level with the periodic time to run. The module that any plan is monitored by routine CMonitorMgr will call Register () 721. This most at last module be added into the circulation bidirectional chain table variable m_LIST_monitor725 of routine CMonitorMgr. Program flow of the present disclosure control monitoring routine operationally in dynamically determine to need the quantity of monitored module, and correspondingly increase or reduce the distribution of corresponding storer.
Any given module, thread or function are about monitoring only to be registered once. If attempting to attempt second time Module registers, so routine CMonitorMgr can not register this module and return negative response for the request received. Fig. 8 and 9 respectively illustrates the orders registering 800 and cancellation 900 monitoring from routine CMonitorMgr. In order to remove module, thread or function from routine CMonitorMgr, routine CMonitor_TimeMinMax object reference routine Unregister () 722. For the received cancellation from monitoring, if having found this module, thread or function in routine CMonitorMgr, so routine CMonitorMgr removes this module from list and returns response certainly. If not finding this module, thread or function items when nullifying, so the request received will be sent negative response by routine CMonitorMgr.
Figure 10 shows precedence diagram 1000, and it has the details of the execution about routine CMonitorMgr class 1005. CMonitorMgr carrys out working procedure current control monitoring routine periodically to plan. This CMonitorMgr execution time interval according to system from a few microsecond by several seconds not etc., and can be configured on system operation time. Use wheel to ask and/or interrupt time-out and run the periodic inspection to each registered module under routine CMonitorMgr class. When receiving time-out event 1010, routine CMonitorMgr starts to monitor registered thread, function or module.
Figure 11 illustrates the execution 1100 of program flow control monitoring routine. If variable " Limit " is beyond the maximum restriction configured or falls under the minimum limit of configuration, so will call interface routine DevExecutionFailure () and take the specific alarm of factory and/or action. This alarm and/or action can be rewritten by equipment development person, to give equipment specific action. When not needing minimum limit to check, m_ulMimTimeLimit will be set to NO_LIMIT_CHECK, can not check lower limit to show. Similarly, this can be applied to maximum time restriction.
Figure 12 shows schema 1200, it illustrates when TriggerTime () class receives the routine performed when calling from just monitored module. The timing register based on interruption shown in schema 1200 can be used to examine whether CMonitorMgr self performs correctly. Routine starts from starting block 1205. Block 1210 is implemented the determination of the active program current control monitoring to whether. If have activated, block 1215 obtaining the snapshot (snapshot) of current time, in block 1215, calculates the time of disappearance subsequently. Block 1225 being determined, whether this is perform the first time after being reset from this routine. If it does, so obtain the minimum time value from triggering the time in block 1230 last time. If, so in block 1235, mark "true" is not distributed to reset after first time perform relevant variable. Block 1240 is implemented from once trigger the time the calculating of maximum time value, subsequently before this routine terminates in block 1250, by the upper set of time that once triggers for equaling current time in block 1245. If CMonitorMgr self in execution, so will not call security function to be set in a safe condition by corresponding plant processes.
Figure 13 shows schema 1300, it illustrates a routine, and when this routine performs, this routine is determined by whether the module of program flow control monitoring routine monitoring has, within the restriction expected, the execution number of times being associated. Routine starts from starting block 1305. In block 1310, check whether variable " WithinLimitStatus " equals "true", subsequently in block 1315, check whether monitoring activates. If monitoring is not activated, so routine continues to block 1355. If monitoring activates, so in block 1320, check whether variable " MinTimeLimit " equals variable " NO_TIME_LIMIT ". If equal, in block 1325, so implement test, to determine whether variable " MinTime " is less than variable " MinTimeLimit ". Block 1330 is implemented check, to determine whether variable " MaxTimeLimit " equals variable " NO_TIME_LIMIT ". Block 1335 obtains the snapshot of current time, and calculates variable " GetElapsedTime ", in block 1340, obtain variable " Maxtime " subsequently. Block 1345 being determined, whether variable " MaxTime " is greater than variable " MaxTimeLimit ". If be greater than, then it is determined that whether the state of variable " WithinLimit " equals "false". Block 1355 returns the state of monitored module. When the module execution time exceeds acceptable scope, return corresponding module error condition.
As shown in the order table 1400 in Figure 14, performing interface routine when module generation fault, DevExecutionFailure () is for monitoring function, and thread or CMonitorMgr self can produce alarm in default situations. Default-action can be rewritten by equipment development person, to have the specific action of factory, such as turns off certain part equipment specific.
Many times, it is desirable to security function is performed with predetermined order. As with reference to described by Figure 15 and 16 and monitor safety order as shown in order table 1500 and schema 1600 and perform. Manipulate variable " SSequenceExecution " 1505, " bExecutionStart ", " Ushort " of boolean's type and " SequenceFailed () " 1515 of " ushSeqNum " 1510 and void type as illustrated in fig. 15. Safe order routine starts from starting block 1605. In block 1610, variable " bExecutionStart " is set to "true", and in block 1615, variable " ushSeqNum " is set to zero. In block 1620, check variable " ushSeqNum ", to determine if the order equaling previously execution. If equaled, so it is set to equal variable " ExecutedSequence " by variable " ushSeqNum " in block 1625. If inequal, so by variable " SequenceExecutionFailure () " set in block 1630. Whether all orders complete to implement test in block 1635. If order does not complete, so routine returns block 1620. If order completes, so before this routine terminates in block 1645, in block 1640, variable " bExecutionStart " is set up and equals "false".
